Combined optimisation of metal hot forming line with induction pre-heating

This paper discusses a system approach for combined optimization of metal hot forming manufacturing line with induction pre-heating. This system approach takes into consideration the whole sequence of the interrelated technological operations including billet heating by induction, its cooling during transportation and subsequent plastic deformation during hot working. All theses subsequent processes will be considered as a technological complex and combined optimization criteria will be used for its optimization. Depending upon application, metal hot working operations may be represented by forging, rolling, stamping, upsetting, extrusion and other operations where metal undergoes plastic deformation.
